Haircut...what's your vote??

So, as our trip down to Myrtle Beach approaches, so does my yearly haircut with my favorite stylist.  But, the question is, what to do with my hair... I'm torn between letting it grow and just cutting it all off again, or trimming it/styling it into a nice little bob.  So, here are some pics of past styles...what's your vote:

Oh, and thinking of going red again...gotta cover those grays!!
